Sub-report summary fields

Question

I have two sub-reports on a report. Each of these sub-reports have a quantity summary on them. I want to find the difference between these two summary totals.
So let's say Sub(A) total is 200 and Sub(B) total is 25, is there a way to subtract the 25 from the 200 and bring that total to the main report?

Answer 1

HI SD, 
1.you have share the value to main report from both sub report by using formula .
2.Sub Report Formula 
For A Sub Report  
shared numberVar Aqty; 
Aqty := Sum ({Command.Qty})
For B Sub Report  
shared numberVar Bqty;  
Bqty := Sum ({Command.Qty})
3.Main Report Formula 
Aqty  
shared numberVar Aqty; 
B Qty 
shared numberVar Bqty;
4.you can create final formula for different Aqty-Bqty
5.you should put formula in both sub report and you should place the main report formula in below of sub report then only it will work. -Rajesh N
